Answer 1

i'm guessing a bit here but I think you're trying to input a city number (which relates to the index of the city_price array) and number of tickets a person wants to buy. Then you want to show the user how much their 'order' costs in total? If so you want something like this:



double city_price[6] = {56.79, 105.69, 93.49, 155.99, 87.49, 73.99};

int cityNumber = 0;

int tickets = 0;

double totalCost = 0;

char response;



do

{

cout << endl <
cin >> cityNumber;

do

{

cout << endl << endl <<"How many tickets do you wish to purchase?";

cin >> tickets;

}

while (tickets < 1 || tickets > 5)



cout << endl << endl << "The cost is: " << city_price[cityNumber];

cout << endl << endl;

cout << "City and Price:" << setw(7) << city_price[cityNumber] << endl;

cout << "Number of tickets:" << setw(7) << tickets << endl;

cout << "-------------------" << endl;

cout << "Your cost:" << setw(7) << city_price[cityNumber] * tickets << endl;





cout << "Do you wish to purchase more tickets? (Y/N): ";

cin >> response;

}



while (response == 'Y' || response == 'y');

Answer 2

You haven't defined what "tickets" is. You have a statement that says:

tickets = 0<5;

What does that mean? If tickets is a bool, then it has the value true (since 0 is less than 5). However, I think you mean somethign else, but I can't even guess at it.



The other problems is that you're multiplying 16 numbers with this non-existent tickets - C++only allws you to multiply one number at a time.

Answer 3

Its nice to give him the answer, but better to include his mistakes.



You didn't declare tickets and cost and then tried to use them.
